[Zope] catalog reindex question

[Sean Kelley]

I have a question about catalog indexing.  I have a product that when 
and item is edited, the catalog listing shows the item twice.  Once with 
info from before editing and once with the updated info.  The python 
script which is editing the item has the lines:

 self.reindex_object()
 if REQUEST is not None:
     return self.index_html(self, REQUEST)

Is there a mistake here?  How does one update the catalog correctly?  I 
am using zope 2.4.3
